What data it sees

Do you need an account

No: the server works without sign-in

Pay-per-call x402 tools for AI agents. Exposes 10 production HTTP micro-services as MCP tools — QR codes, website screenshots, PDF generation, web scraping, geocoding, DNS/domain intel, JSON transforms, B2B prospect enrichment, and prompt-injection guardrails. Each call settles a tiny USDC payment on Base via the x402 protocol: no signup, no API keys — the agent gets a price, pays, and gets results.
